I tell my students, if you're interested in marine biology or llama farming, follow that string. Yes, it will probably take you a longer time to write that book, but it's not a race. That's another great thing about being a writer: you don't age out.

The trajectory of my writing has moved further and further away from autobiography. My first stories in Confessions of a Falling Woman worked familiar territory - places I had lived, people I knew, my life as an actor in New York - and many were prompted by or grounded in personal experience.

I always think, OK, this is good, but I'll do it better next time. "And so we beat on, boats against the current. . ." It may not be the recipe for a life of contentment, but that imperfectability is what makes writing such an engaging endeavor, something you can do for the rest of your life and not get bored.

I just can't fathom tweeting, and I'd rather spend my time writing a book than a blog, but I rather grudgingly agreed to a Facebook page. I had a brief, intense romance with Facebook. It's weirdly addictive, but anything that time-sucking is a danger for a writer who writes as slowly as I do. Now I post only occasionally and nothing very confessional. I think I'm carbon dating myself as I speak.

With the historical fictions, I was already doing so much research, and so much of the stories was anchored by historical truth that the move to nonfiction didn't feel all that dramatic - just another half-step to the right.

Unless you're Stephen King or Joyce Carol Oates, no one's going to recognize you on the street, and you're promoting your book, not yourself.

When I left the theatre and turned to writing, one of the big pulls was that, unlike the theatre, I didn't have to wait to be hired before I could do my art. That was huge. But you still have to figure out how to support your habit; it's rare and lucky when art pays the bills.
